• What is the cause and solution for SAP error message APB_FPM_TEST020 - Leaf nodes cannot be dropped at Root level nodes ?

  The SAP error message APB_FPM_TEST020: Leaf nodes cannot be dropped at Root level nodes typically occurs in the context of the SAP FPM (Floorplan Manager) or when working with the FPM configuration in the SAP Business Suite. This error indicates that there is an attempt to remove or drop a leaf node (a node that does not have any child nodes) from a root-level node in a hierarchical structure, which is not allowed.
  Cause:
  
  Hierarchical Structure Violation: The error arises when you try to delete a node that is a leaf node but is positioned at the root level of a hierarchy. In many configurations, root nodes are expected to have child nodes, and leaf nodes should be part of a deeper hierarchy.
  Incorrect Configuration: The configuration of the FPM application might be incorrect, leading to an attempt to manipulate nodes in a way that violates the expected structure.
  
  Solution:
  
  Check Node Structure: Review the hierarchical structure of your nodes. Ensure that you are not trying to drop a leaf node that is incorrectly positioned at the root level.
  Adjust Node Levels: If you need to remove a leaf node, ensure that it is not at the root level. You may need to move it to a different level in the hierarchy before attempting to delete it.
  Use Correct Methods: Ensure that you are using the correct methods or functions to manipulate the nodes. If you are using a custom implementation, verify that the logic adheres to the expected node hierarchy rules.
  Consult Documentation: Refer to the SAP documentation for FPM and the specific application you are working with to understand the expected node structure and manipulation rules.
  Debugging: If the issue persists, consider debugging the application to trace where the error is being triggered and to understand the context better.
